T all whom. "it may canoe m Be it known that l, LYMAN A. TRULL, acitizen of the United States, and a resident of lWill-iamsport, in thecounty of lily coming and State of Pennsylvania, have invented certain.new and useful Improvements in Vulcanized Boots and Shoes, of which thefollowing is a full, clear, and exact description. 1

This invention relates more particularly to rubber-soled shoes of thetype having a. canvas upper and an outer sole of rubber.

The invention has for its object to provide a shoe of the said typewhich closely resembles a Goodyear Welt shoe, and in which the margin ofthe outer sole is, efl'ect,secured to the inner sole by permanentmetallic or other fastenin means Which is entirely concealed.

Theinvention will be understood by reference to the accompanyingdraw-rings, in which:

Fig. 2 is an enlarged sectional detail view illustrating the relativearrangement of the parts.

the drawings, the be made of fiber board, leather or other suitablematerial is first placed upon the bottom of the last. T he upper 2 ofcanvas or other suitable fabric is then shaped to the last and itsmargin 3 turned over and secured to the inner sole, preferably by tacksthe points of which are clenched to theinner sole by striking againstthe bottom oithe las It is to be understood however that, if desired,stitches, cement, or other means may be employed instead of tacks tosecure the overthe upper to the inner sole. The. welt strip 5 oE-rubbercomposition is next applied about the edge of the shoe, and is sodispose. that its inner portion ("7 lies upon overlasted margin 3 of theupper, while its outer portion 7 protrudes beyond the upper, giving tothe shoe the appean ance and the advantages of a leather shoe of theWelt type. Preferably, the upper surface 8 of the protruding'portion 7of the Welt strip is formed With transverse ridges 9 to simulate-theindented stitching of a leather shoe. It will be noted that thepor tionof the strip which lies upon the folded argi'n 3 of the upper is reducedin thickness so as to provide a shoulder against which the upper r stsat the line of fold of the said margin, and a second shoulder lyingagainst the edge of a fabric binder sheet 11. By this means the Welt isso positioned with respect to the upper as to enhance the appearance ofthe shoe, and the said shoulders aid in resisting the strains upon theprojecting margin of the outer sole which tend to pull the latter loosefrom the insole.

After the welt strip has been applied, the space Within its inner marginis filled with suitable vulcaniZa-ble plastic composition 10 to levelthe bottom of the shoe.

The binder sheet 11 is next applied.

This sheet is composed. of fabric frictioned or otherwise coated on bothsides with rubber. The binder sheet is employed to enable at strongvulcanized union to be formed between the rubber outer sole and thefiller. The binder sheet in the present instance overlaps the tape likeextension of the Welt strip Which lies over the margin 3 of the upper,and metallic fasteners 12 employed to secure the wait st ip to the innersole are driven through the binder sheet. Any other suitable fasteningmeans may be, employed in place of the metallic fasteners.

The toe portion of a shoe is obviously subjected to greater strains inservice than the other parts. For the purpose of strengthening this partof the shoe and of providing a body of fabric of increased thickness toprevent the staples from tearing through the binder sheet when heavystrains are encountered, a ,toe reinforcing piece 13,

formed of fabric coated on both sides With rubber, is employed. Thispiece is of a size and shape corresponding with the toe portion of thebinder sheet on which it is superposed. The staples 12 used to'securethe toe portion of the binder sheet are driven. through this piece. r

The rubber outer sole 14c and heel 15, which may be formed integrally orseparately as desired, are next cemented in place.

They are made of sufficient size to extend to I the extreme ridge of theWelt to give the deized together.

sired strength and body to the boot or shoe and the neat and attractiveappearance characteristic of a leather shoe.

When the Shoe has been built up asset forth it is finally subjected tovulcanization whereby the parts are permanently vulcan- Duringvulcanization the outer sole and welt strip are so united as to becomein effectan integral structure. Therefore the staples '12 afford meansby which the outsole near its margins is secured to the inner sole bypermanent fasteners which are entirely concealed.

Shoes manufactured in accordance with the invention are of attractiveappearance and possess greater strength and wearing qualities than anyof the other shoes of this character heretofore known.

Although one of ,the preferred embodiments of the invention has beendescribed, it is to be understood that various modifications in thenumber, form, material and arrangement of the parts may be resortedtoWithout departingfrom the spirit and scope or sacrificing any of theadvantages of the invention defined in the appended claims.

-Havin thus described my invention, what I c aim and desire to protectby Letters Patent is: I

1. A shoe comprising an insole, an upper having its lower margin turnedover upon the insole, a vulcanized outer sole, and a vulcanized weltstrip intermediate the insole and outsole, the said welt strip beingsecured to the insole by metallic fastening devices extending throughthe said margin of the upper.

2. 'A shoe comprising an insole, an uppe having its lower margin turnedover upoil 1 the insole, a vulcanized outer sole, and a}- vulcanizedwelt strip intermediate the in-'- sole and outsole, Secured to theinsole by metallic fastening devices extending through the margin of theupper and being integrally united with the outsole by vulcanization.

3. A shoe comprisi'i gan insole, an upper having its lower margin foldedover upon the insole, a vulcanized outer sole, a'nda vulcanized weltstrip intermediate the insole and outsole and coextensive with themargin of the latter, the said Welt stri being formed with a shoulder aainst w ich the upper rests at the line of ibld of said margin, andbeing secured to the insole by metallic fastening devices extendingthrough the margin of the upper;

4. A shoe comprising an insole, an upper having its lower margin turnedover upon BOJshe insole, a vulcanized outer sole, a vulcanized weltstrip coextensive with the mar gm of the outsole, and formed with atapethe said welt strip being like extension lying intermediate thesoles,

and concealed mechanical fasteningjmeans securing together said insole.margin and extension.

5. A shoe comprising an insole, an upper having its lower margin turnedover upon 1 the insole, a vulcanized outer solo, a vulcanized welt stripcoextensive with the margin of the outsole, and formed with an extensionof reduced thickness lying intermediate the soles, said strip beingsecured to the insole by metallic fastening pieces ex tending throughthe margin of the upper.

6. A shoe comprising an insole, an upper having its lower margin turnedover upon the insole, avulcanized outer sole, 9,, vulcanized welt stripcoextensive with the mar.- gin of the outsole and formed with anextension of reduced thickness lying intermediatc the soles, the saidwelt strip being so,-

beingsecur ed tbgether by vulcanization, and

metallic fasteners interengaging the welt strip, binder piece, and innersole.

8. A rubber sole shoe comprising an inner sole, an upper having a marginoverlasted on the inner sole and secured thereto, a weltstripoverlapping the overlasted margin of the upper, a binder piece securedto the i inner sole both by vulcanization and b Cnietallic fastenerspassing through the iweli \strip, a toe reinforcing piece, and an outer'soleiunited to the welt strip and binder piece by vulcanization.

9. A rubber sole shoe comprising a fiber board inner sole, a fabricupper having a margin .overlasted on the inner sole and socured theretoby metallic fasteners, a welt strip having an outer margin ,protruding Imargin overlapping the overlasted'margin I beyond the sides of the upperand an inner of the upper, a filler within the space bounded by theinner. margin of t h6 wen stripga fabric binder piece secured 111 081-tion vulcanization, a fabric toe rein orcing piece united tofthe binderpiece, metallic fasteners securin the toe reinforcing piece, binderpiece and nner sole together,-and an outer sole united to the binderreinforcing piecg by vulcanization.
